Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
The method that the utility model uses is the mobile silk thread video display technology method of water body.Device mainly contains three parts and forms: hermetically sealed video shows probe, silk thread frame and probe holder.Video shows that probe is a main device; Form by camera 9, video optical multiplexer 10, hyalomitome shell and waterproof filling glue; See Fig. 1, cable outlet and 2 hangers 2 are arranged on the shell, hangers is used for probe is installed on probe holder; And can Free Slosh, be connected through the waterproof threaded connector with shell.The camera lens face of camera is close to the hyalomitome bottom, the fixing and waterproof with the epoxide-resin glue of interior filling.The silk thread frame is made up of set collar, steel bar and silk thread.Set collar is used for the silk thread frame is fixed on the bottom of probe, removable jew, the time spent is loaded onto, and has screw tightening to get final product, and the time spent is not unloaded.Silk thread is used to reflect the flowing velocity and the flow direction of water body, sees Fig. 2, and the time spent fastens, and the time spent does not take off and gets final product.Probe holder is made up of cross bar, steelframe, skidding and stressed steel cable, and cross bar is used to wear to be hung video and show probe, and skidding makes the probe holder can slippage, and steelframe can make probe erect, and stressed steel cable moves whole device.Whole probe holder all is detachable, connects with screw nut.
The first step, the assembling of device:
At first be that material is bought: the material and the device that need to buy have: camera, fiber optic, organic glass cylinder and sheet material, single-mode fiber, power lead, epoxy resin filling glue, organic glass special glue, waterproof threaded connector, thin steel bar, silk thread, skidding, stressed steel cable and screw nut etc.
Next be material processing be connected: the organic glass cylinder is processed into outside diameter 10cm, wall thickness 0.8cm, the large cylinder 3 of long 15cm; With 2 diameter 10cm of methacrylate sheet processing; The plectane of thickness 1 cm, wherein 1 is used as bottom 1, with the organic glass glue special it is sticked in the bottom of large cylinder 3; In addition the piece plectane is as top cover 4, at one of its position, center of circle processing and the supporting internal thread hole of waterproof threaded connector.Camera 9 is put into large cylinder 3, and make the camera lens face be close to bottom, be applied to the camera lens outside, make it temporarily fixing with a small amount of epoxide-resin glue; Put into fiber optic 10, and be connected, pass waterproof threaded connector 5 with camera 9, optical fiber cable 7 and power lead 6; All be full of large cylinder 3 with epoxy resin, make camera, fiber optic become complete waterproof body 8, before epoxy resin is not dried as yet; Cover top cover 4, coat the organic glass glue special, make whole probe moulding and can prevent water under high pressure.Process 2 hangers 2, with the organic glass glue special it is sticked on the large cylinder, video shows that probe has just machined.
With 1 internal diameter 10cm of organic glass processing, the annulus 13 of thickness 5mm is processed into L type 12, one ends with the thin steel bar of diameter 3mm and is threaded with annulus 13 usefulness, and other holds and is connected with silk thread 11, and the silk thread frame machines at this point.
With diameter 10 mm, the stainless steel bar of long 50cm is as cross bar 14, both end thread; With the stainless steel bar processing steelframe 15 of diameter 5mm, the junction all connects with screw nut, for detachable, loads onto skidding 16, and probe holder machines at this point.
Be whole assembling at last, be about to video and show that probe, silk thread frame and probe holder integral body assemble up.Before probe holder does not connect with screw nut as yet, earlier video is shown that probe hangs on the cross bar through 2 hangers, all couples together probe holder again with screw nut; The silk thread frame is fixed on the bottom 1 of probe, more stressed steel cable 17 is tied up on the probe holder.
Second goes on foot, and device is rendered to the privileged site of water body:
With the pressurized tunnel is example, and device is put into the tunnel mouth, because tunnel tilts, device can rely on the gravity of self, by means of skidding device is moved to predetermined position.
The 3rd step, the flow velocity and the flow direction of measurement water body:
Before measurement, close the intake-outlet of pressurized tunnel, the interior water body of tunnel is remained static generally, begin afterwards to measure.
Make stressed steel cable stressed, promptly slowly spur stressed steel cable, device is slowly moved, stop to move 5 minutes behind the whenever mobile 1m, observe the drift situation of silk thread through video.If device position pressurized tunnel does not have the seepage situation, then the drift direction of two rhizoid lines is at random, if there is seepage, then installs the position and just has flowing of water, and the drift direction of two rhizoid lines is in full accord.The size of flowing velocity is with the drift degree reflection of two rhizoid lines, and the drift degree is big more, and flow velocity is just big more, and seepage is just serious more, otherwise flow velocity is just more little, and seepage is not serious.Flow to also and reflect through silk thread, the direction of silk thread drift is exactly the flow direction of water, further confirms the seepage mouth locality of pressurized tunnel whereby.
By equidistantly measuring, after tunnel measurement of length to be measured finishes, device is proposed, unload each ingredient.
